Listing Notes

BEYOND THE ORDINARY - DESIGNER'S PRIVATE HOME. MOVE RIGHT IN. A truly turnkey Classic Six, masterfully reimagined for modern living and effortless entertaining, with lovely Lenox Hill views and glimpses of Central Park throughout. A striking gallery with Bianco Bello marble floors and refined architectural details opens to a sun-filled corner living room with a gas fireplace, flowing seamlessly into a formal dining room and sleek open kitchen. Finished with rift-sawn oak cabinetry, Bianco Bella marble, and top-of-the-line Sub-Zero and Wolf appliances, the kitchen is both elegant and highly functional, complemented by a stylish butler's bar. The residence offers two beautifully appointed primary suites, each with open views and luxurious marble baths. A third room, originally a small staff bedroom, has been reimagined as a petite guest bedroom or office, complete with its own spa bath. A Giorgio Armani powder room adds a distinctive finishing touch. Additional features include wide-plank oak floors, new Marvin windows, sound insulation throughout, new central air conditioning, a vented washer/dryer, and a private storage unit that transfers with the apartment. 21 East 66th Street is a boutique prewar full-service condominium with just 19 residences, ideally located half a block from Central Park in one of the Upper East Side's most coveted locations, moments from the neighborhood's finest dining, shopping, and transportation.
